@zepdrix heyy you busy rn?
Arithmetic means we're `adding or subtracting` something each time to get to the next term.
To get to k, we have to add some common difference to 32, ya? Let's call that value d.
So we'll say that our k is equal to 32 plus some unknown number.\[\large\rm k=32+d\]
How do we get to 3? Well we add d again, right?
yeah, but how do we find out what d is?
So to get from 32 to 3, we add this common difference twice.|dw:1450402954155:dw|
kk i gotcha
Therefore, this value 3 is equal to 32, with 2 d's added to it.
Now that we've gotten the k out of our way for now, we can solve for d, ya? :)
ummm yeah i get it
so do we subtract 32 from 3?
Ya that seems like a good first step in solving for d.
ok so -29=2d
but are we gonna end up with a decimal?
Unfortunately ya :p
ok lol so then d= 14.5
do you subtract that from 32?
oh right its negative
Yes, either subtract 14.5 from 32, or add -14.5 to 32 lol
lol my bad. so then the answer is 17.5, right?
Yes. Good job. Here is a good way to check your work also. Let's add -14.5 to it again, and see if it gets us to 3. 17.5 - 14.5 = 3. Yay.
ok thanks zep! if you don't mind me asking, how long are you gonna be online?
lol maybe an hour :) i dunno, maybe longer. I'm not an employee or anything so it's hard to say haha
ok cool just wondering cos I'm studying tonight ^-^
